独立项目-建立Web服务器-02
一、设置服务器站点读取数据库内容
1.修改表中的CreateTime，如下图所示：
2.在表中（之前创建的表），填写数据，如下图所示：
二、VS2017中的脚本创建
1.在VS2017中，打开之前创建的工程“WebAccount”工程，
创建Entity文件夹。如下图所示：
2.创建普通类，AccountEntity.cs类
namespace WebAccount.Entity { public class AccountEntity { public int Id { get; set; } public string UserName { get; set; } public string Pwd { get; set; } public int YuanBao { get; set; } public int LastServerId { get; set; } public string LastServerName { get; set; } public DateTime CreateTime { get; set; } public DateTime UpdateTime { get; set; } } }
3.在Models文件夹中，创建AccountDBModel.cs类
using System; using System.Collections.Generic; using System.Data.SqlClient; using System.Linq; using System.Web; using WebAccount.Entity; namespace WebAccount.Models { public class AccountDBModel { #region 创建单例 /// <summary> /// 锁 /// </summary> private static object lock_object = new object(); private static AccountDBModel _instance; public static AccountDBModel Instance { get { if (_instance == null) { lock (lock_object) { if (_instance == null) { _instance = new AccountDBModel(); } } } return _instance; } } #endregion #region 属性 //视图里面的服务器资源管理器进行设置并且添加的 private const string connStr = @"Data Source=DESKTOP-63OA6R3\DEAN;Initial Catalog=DBAccount;Integrated Security=True"; #endregion /// <summary> /// 根据账户id，从数据库获取账号信息 /// </summary> /// <param name="id"></param> /// <returns></returns> public AccountEntity Get(int id) { //建立数据库连接 using (SqlConnection conn = new SqlConnection(connStr)) { //数据库打开 conn.Open(); //建立执行对象 SqlCommand cmd = new SqlCommand("Account_Get",conn); //设置方式为使用存储过程 cmd.CommandType = System.Data.CommandType.StoredProcedure; //添加查询参数 cmd.Parameters.Add(new SqlParameter("@Id", id)); using (SqlDataReader dr = cmd.ExecuteReader(System.Data.CommandBehavior.CloseConnection)) { //如果有数据 if (dr.HasRows && dr.Read()) { AccountEntity entity = new AccountEntity(); entity.Id = dr["Id"] is DBNull ? 0 : Convert.ToInt32(dr["Id"]); entity.UserName = dr["UserName"] is DBNull ? string.Empty : dr["UserName"].ToString(); entity.Pwd = dr["Pwd"] is DBNull ? string.Empty : dr["Pwd"].ToString(); entity.YuanBao = dr["YuanBao"] is DBNull ? 0 : Convert.ToInt32(dr["YuanBao"]); entity.LastServerId = dr["LastServerId"] is DBNull ? 0 : Convert.ToInt32(dr["LastServerId"]); entity.LastServerName = dr["LastServerName"] is DBNull ? string.Empty : dr["LastServerName"].ToString(); entity.CreateTime = dr["CreateTime"] is DBNull ? DateTime.MinValue : Convert.ToDateTime(dr["CreateTime"]); entity.UpdateTime = dr["UpdateTime"] is DBNull ? DateTime.MinValue : Convert.ToDateTime(dr["UpdateTime"]); return entity; } } } return null; } /// <summary> /// 注册账号 /// </summary> /// <param name="userName"></param> /// <param name="pwd"></param> /// <returns></returns> public int Register(string userName, string pwd) { int userId = -1; //建立数据库连接 using (SqlConnection conn = new SqlConnection(connStr)) { //数据库打开 conn.Open(); //建立执行对象 SqlCommand cmd = new SqlCommand("Account_Register", conn); //设置方式为使用存储过程 cmd.CommandType = System.Data.CommandType.StoredProcedure; cmd.Parameters.Add(new SqlParameter("@UserName", userName)); cmd.Parameters.Add(new SqlParameter("@Pwd", pwd)); userId = Convert.ToInt32(cmd.ExecuteScalar().ToString()); } return userId; } } }
4.创建RetValues.cs类：
using System; using System.Collections.Generic; using System.Linq; using System.Web; namespace WebAccount { public class RetValue { public bool HasError; public string ErrorMsg; public object RetData; } }
5.修改AccountController.cs类：
using LitJson; using System; using System.Collections.Generic; using System.Linq; using System.Net; using System.Net.Http; using System.Web.Http; using WebAccount.Entity; using WebAccount.Models; namespace WebAccount.Controllers.api { public class AccountController : ApiController { // GET: api/Account public IEnumerable<string> Get() { return new string[] { "value1", "value2" }; } // GET: api/Account/5 public AccountEntity Get(int id) { return AccountDBModel.Instance.Get(id); } // POST: api/Account public RetValue Post([FromBody]string jsonStr) { RetValue ret = new RetValue(); try { JsonData jsonData = JsonMapper.ToObject(jsonStr); int type = Convert.ToInt32(jsonData["type"].ToString()); string userName = jsonData["UserName"].ToString(); string pwd = jsonData["Pwd"].ToString(); //注册 if (type == 0) { ret.RetData = AccountDBModel.Instance.Register(userName, pwd); } //登陆 else if (type == 1) { } } catch (Exception ex) { ret.HasError = true; ret.ErrorMsg = ex.Message; } return ret; } // PUT: api/Account/5 public void Put(int id, [FromBody]string value) { } // DELETE: api/Account/5 public void Delete(int id) { } } }
三、数据库中的可编程性->存储过程
1.获取，Get存储过程，如下图：
2.注册，Register存储过程，如下图：
四、在Unity中连接数据库，并举例使用
1.创建NetWorkHttp.cs类：
#region 模块信息 // ********************************************************************** // Copyright (C) 2018 The company name // // 文件名(File Name): NetWorkHttp.cs // 作者(Author): Dean1874 // 创建时间(CreateTime): 2018-06-02 18:50:36 // 修改者列表(modifier): // 模块描述(Module description): // // ********************************************************************** #endregion using System; using System.Collections; using UnityEngine; /// <summary> /// Http通讯管理 /// </summary> public class NetWorkHttp : DontDesMonoSingleton<NetWorkHttp> { #region 属性 /// <summary> /// Web请求回调 /// </summary> private Action<CallBackArgs> m_CallBack; /// <summary> /// Web请求回调数据 /// </summary> private CallBackArgs m_CallBackArgs; /// <summary> /// 是否繁忙 /// </summary> private bool m_IsBusy = false; /// <summary> /// 是否繁忙 /// </summary> public bool IsBusy { get { return m_IsBusy; } } #endregion private void Start() { m_CallBackArgs = new CallBackArgs(); } #region 发送web数据 /// <summary> /// 发送web数据 /// </summary> /// <param name="url">地址</param> /// <param name="callBack">回调</param> /// <param name="isPost">是否是请求</param> /// <param name="json">json数据</param> public void SendData(string url, Action<CallBackArgs> callBack, bool isPost = false, string json = null) { if (m_IsBusy) { return; } m_IsBusy = true; m_CallBack = callBack; //如果不是请求 if (!isPost) { GetUrl(url); } else { PostUrl(url, json); } } #endregion #region GetUrl Get请求 /// <summary> /// Get请求 /// </summary> /// <param name="url"></param> private void GetUrl(string url) { WWW data = new WWW(url); StartCoroutine(Request(data)); } #endregion #region PostUrl Post请求 /// <summary> /// Post请求 /// </summary> /// <param name="url"></param> /// <param name="json"></param> private void PostUrl(string url, string json) { //定义一个表单 WWWForm form = new WWWForm(); //给表单添加值 form.AddField("", json); WWW data = new WWW(url, form); StartCoroutine(Request(data)); } #endregion #region 请求服务器 /// <summary> /// 请求服务器 /// </summary> /// <param name="data"></param> /// <returns></returns> private IEnumerator Request(WWW data) { yield return data; //返回数据，进行回调 //设置当前不繁忙 m_IsBusy = false; //如果没有错误 if (string.IsNullOrEmpty(data.error)) { //一样视为存在错误 if (data.text == "null") { if (m_CallBack != null) { m_CallBackArgs.HasError = true; m_CallBackArgs.ErrorMsg = "未请求到数据"; //回调 m_CallBack(m_CallBackArgs); } } else { if (m_CallBack != null) { m_CallBackArgs.HasError = false; m_CallBackArgs.Data = data.text; //回调 m_CallBack(m_CallBackArgs); } } } else { if (m_CallBack != null) { m_CallBackArgs.HasError = true; m_CallBackArgs.ErrorMsg = data.error; //回调 m_CallBack(m_CallBackArgs); } } } #endregion #region Web请求回调数据 /// <summary> /// Web请求回调数据 /// </summary> public class CallBackArgs : EventArgs { //是否有错 public bool HasError; //错误内容 public string ErrorMsg; //Jason数据 public string Data; } #endregion }
2.创建AccountEntity.cs实体类，和服务器端的一样，可以直接复制过来用。
using System; /// <summary> /// 账户实体 /// </summary> public class AccountEntity { public int Id { get; set; } public string UserName { get; set; } public string Pwd { get; set; } public int YuanBao { get; set; } public int LastServerId { get; set; } public string LastServerName { get; set; } public DateTime CreateTime { get; set; } public DateTime UpdateTime { get; set; } }
3.在实例创景中，创建Test_007_Http_00.cs类
#region 模块信息 // ********************************************************************** // Copyright (C) 2018 The company name // // 文件名(File Name): Test_007_Http_00.cs // 作者(Author): Dean1874 // 创建时间(CreateTime): 2018-06-02 19:20:19 // 修改者列表(modifier): // 模块描述(Module description): // // ********************************************************************** #endregion using LitJson; using System; using UnityEngine; public class Test_007_Http_00 : MonoBehaviour { private void Start() { //Get if (!NetWorkHttp.Instance.IsBusy) { NetWorkHttp.Instance.SendData(GlobalInit.WebAccountUrl + "api/account?id=3006", GetCallBack); } //Post if (!NetWorkHttp.Instance.IsBusy) { JsonData jsonData = new JsonData(); jsonData["type"] = 0;//0=注册 1=登陆 jsonData["UserName"] = "text322"; jsonData["Pwd"] = "123"; NetWorkHttp.Instance.SendData(GlobalInit.WebAccountUrl + "api/account", PostCallBack, isPost: true, json: jsonData.ToJson()); } } private void PostCallBack(NetWorkHttp.CallBackArgs obj) { if (obj.HasError) { Debug.Log(obj.ErrorMsg); } else { RetValue ret = JsonMapper.ToObject<RetValue>(obj.Data); if (!ret.HasError) { Debug.Log("用户编号=" + ret.RetData); } } } private void GetCallBack(NetWorkHttp.CallBackArgs obj) { Debug.Log(obj.Data); if (obj.HasError) { Debug.Log(obj.ErrorMsg); } else { AccountEntity entity = LitJson.JsonMapper.ToObject<AccountEntity>(obj.Data); Debug.Log(entity.UserName); } } }
4.运行脚本使用。
